Why Would a Company Not Patent Its Best Idea? Protection Without Publication

A patent is a deal with the state, granting the holder a monopoly for a fixed period, typically twenty years, in exchange for publishing the invention in enough detail that anybody skilled in the field could reproduce it once the term ends. Secrecy offers no monopoly and no legal exclusivity over the information itself, and instead protects against specific wrongful acts, namely acquiring the information by improper means or disclosing it in breach of an obligation. It lasts as long as the secrecy does, which may be forever, and ends completely the moment the information becomes public by any route. The two are therefore opposite strategies rather than alternatives of the same kind.

Several factors push a decision one way or the other:

• •Whether the invention can be worked out by examining the product
• •How long the commercial advantage is expected to last
• •Whether competitors are likely to develop it independently
• •Whether the subject matter is patentable at all
• •How many people inside the organisation must know it
• •The cost of obtaining and enforcing patents in many countries

Certain formulations have been kept confidential for over a century and are the standard illustrations. The recipe for a well-known soft drink has never been patented, which would have placed it in the public domain decades ago, and the company has maintained an elaborate apparatus of restricted access around it. Industrial processes, customer lists, manufacturing tolerances, supplier arrangements and software algorithms are protected this way routinely and far more often than the famous cases suggest. Against that, a secret provides no protection at all against somebody who works it out independently or takes the product apart and determines how it was made, which is entirely lawful and is why anything visible in a product is usually patented instead.

Protection for confidential information developed unevenly and has been harmonised comparatively recently. It grew out of general principles about breach of confidence and unfair competition rather than from any dedicated statute, which meant the rules differed substantially between countries and were hard to enforce across borders. The United States passed a uniform state-level act from 1979 and a federal statute in 2016 allowing civil claims in federal court. The European Union adopted a directive in 2016 requiring member states to provide a common minimum standard, including a shared definition and remedies. An international trade agreement had already required signatories to protect such information from 1995. The direction of travel is towards treating it as a recognised category of intellectual property rather than as a species of contract or confidence.

Legal protection depends on the holder having actually treated the information as confidential, which courts examine closely when a claim is brought. That means demonstrable measures, including restricting access to those who need it, confidentiality agreements with employees and suppliers, marking documents, controlling physical and electronic access, and having a policy that is followed rather than merely written. A holder who failed to take reasonable steps generally cannot complain when the information escapes. The commonest route by which secrets are lost is departing employees, which has produced a large body of litigation about what a former employee may take in their head, and restrictive covenants attempting to prevent them working for competitors are enforceable only within narrow limits in most jurisdictions.

A patent grants a monopoly for a fixed term in exchange for publishing the invention, while secrecy grants no exclusivity, lasts as long as the confidentiality does and ends the instant the information becomes public. Whether the invention can be worked out from the product is the decisive question. Protection depends on having actually restricted access, and departing employees are the commonest route by which such information escapes.
